CA3130E

Overview

The CA3130E is a single-channel, general-purpose operational amplifier manufactured by Intersil (Renesas). It features a BiMOS architecture combining MOSFET inputs with CMOS outputs. Key electrical parameters include a gain-bandwidth product of 15 MHz and a slew rate of 30 V/µs. The device operates on dual supplies ranging from ±2.5 V to ±8 V or a single supply from 5 V to 16 V. Input offset voltage is typically 5 mV, with an input bias current of 0.03 nA. It is housed in an SOIC-8 surface-mount package.

Feature Summary

• BiMOS technology integrating high-impedance MOSFET input stage with low-output-impedance CMOS output stage
• High slew rate capability for fast signal transitions
• Low input bias current suitable for precision applications
• Wide operating voltage range supporting both single and dual supply configurations

Applications

• Sample-and-hold circuits
• Integrators
• Transducer amplifiers
• Photodiode amplifiers

Procurement Notes

Verify the specific suffix against the manufacturer's latest datasheet to confirm pinout compatibility and electrical tolerances. Ensure the ordering code matches the required package type and temperature grade. Cross-reference the manufacturer part number with authorized distributors to confirm current availability and authenticity before placing orders.

Selection Notes

Select this component when high input impedance and fast slew rates are required in a single-supply or dual-supply environment. Compare input offset voltage and bias current specifications against application requirements. Consider the SOIC-8 package constraints for PCB layout. Evaluate thermal performance if operating near maximum voltage limits.

Part Context

The CA3130 series belongs to Intersil's family of BiMOS operational amplifiers. These devices were designed to offer the best of both MOS and bipolar technologies. The CA3130 specifically targets applications requiring high speed and low input current. It serves as a legacy component in Renesas's portfolio, often replaced by newer iterations with improved specifications.

Replacement Considerations

Check for direct replacements such as the CA3130A or CA3130EZ for minor specification variations. Verify pin compatibility with generic op-amps like the LM318 if higher drive current is needed. Confirm that substitute components meet the same BiMOS input characteristics and voltage ranges.
